Title: Improvements relating to control means for an internal combustion engine whereby such engine is employable as a brake by control of its exhaust
IPC: F01L13/00
Filed: 1953-05-13
Abstract: 734,058. Regulating. DAIMLER-BENZ AKT.GES. May 13, 1953 [May 13, 1952], No. 13390/53. Class 7(6). [Also in Group XXXI] A throttle valve k in the exhaust pipe which may be closed manually by a lever h to cause engine braking is operatively connected to the clutch pedal K and to the accelerator control rod c so that the fuel or fuel-air mixture supply is cut off when the valve k is closed, the connection being such that depression of the clutch or accelerater pedals during exhaust throttling first opens the valve k, restores the fuel or fuelair mixture supply, and finally, in the case of the clutch pedal, opens the clutch. The valve k is connected by a link l to a lever a which is connected by a rod b having a resilient portion q to the clutch pedal K and has an upstanding end co-operating with stops g, f, ontheaccelerater rod c which operates the fuel or fuel-air mixture control lever o through a lost-motion slot. An idling stop d co-operating with a stop e on the rod c is pivoted and adjusted by a cable through a resilient connection n. When the valve k is closed for braking, the lever a contacts the stop f and moves the accelerater rod c to override the idling stop d and cut off the fuel or mixture supply. Depression of the clutch pedal K while the valve k is closed first opens the valve k and then moves the accelerater rod c to restore the fuel supply before the clutch is opened. Similarly, depression of the accelerater pedal when the valve k is closed causes opening of the valve k before the fuel supply is restored. If the engine drives a vehicle drawing a trailer, a brake valve-p for the trailer can be operated from the lever a simultaneously with the initiation of engine braking.

Filed: 1947-05-19
Abstract: 638,424. Packing, &c. G. D. SOC. ANON. May 19, 1947, Nos. 13413, 13414, 13415 and 13416. Convention dates, Oct. 16, Oct. 16, Nov. 14, and Dec. 29, 1945. [Class 94(i)] [Also in Group XXIX] In power transmission from a motor to the operative members of a packing machine comprising pistons actuated by cams on a camshaft driven by a motor, the operative members being actuated by liquid displaceable by the pistons through pipes connected therewith, a reserve supply of the liquid is provided, together with means for replacing liquid lost therefrom. In the construction shown in Fig. 5, a series of cams 5 (one only, shown) on a main drive shaft of the machine engage respective rollers each carried by a plunger 26 mounted in an hydraulic cylinder 22 connected by a conduit 27 to a cylinder 11 having an associated plunger 13. Each plunger 13 is connected with a respective operative machine-member. An air escape valve 34 is provided, and may be spring- loaded so that it also functions as a safety valve. The cylinder 22 is surrounded by a hydraulicliquid reservoir 24 from which leakage is automatically replenished by the action of a valve 25. The valve 25 may be replaced by a port in the cylinder wall connecting the in- .terior of the cylinder and the reservoir, which is uncovered by the piston when at its highest point. Leakage of liquid from the cylinder is minimised by an annular space 36 in the cylinder wall connected with the reservoir. In a modified construction (Fig. 8) of the driven member, a cylinder 66 is mounted on a slide 62. A plunger 44 is associated with a sleeve 45 carrying a roller 51 which engages a surface 52 on a lever arm 53. The operative machine-member is driven by a link 56 connected to a crank 55 rigid with the lever arm 53. The axis of the cylinder 66 may be displaced relative to the slide 62 by means of a screw 63 so that the effective radius of the lever arm 53 may be varied. The cylinder 66 may alternatively be mounted for angular adjustment relative to the machine frame and the surface 52 may be curved instead of linear. In the Specification as open to inspection under Sect. 91, a reserve tank or autoclave is connected with the liquid reservoir 24 the level in the tank being above the highest point in the remainder of the hydraulic system. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to diaphragm valves and diaphragms therefor
Inventor: PRICE RICHARD HECTOR
IPC: F16K7/12
Filed: 1953-05-13
Abstract: 744,071. Elastic valves. SAUNDERS VALVE CO., Ltd. May 13, 1954 [May 13, 1953], No. 13413/53. Class 135. In a diaphragm for a diaphragm valve comprising in the free state a substantially conical resilient member 12 which has a rounded apex 13 and is turned partly inside out as the valve opens, the inner part or all of the clamped margin of the diaphragm when in the free state merges smoothly by means of a sweeping curve 24 into the side of the conical member 12. In this way the sloping part of the margin adjacent the valve bore is placed under compression and the part away from the valve bore is placed under tension so that less effort is required to open the valve and the load on the diaphragm attachment is reduced. The curve 24 is less steep than the conical part and its radius on the side adjacent the valve bore may be twothirds of the radius of the base of the cone. The diaphragm attachment means comprise the usual threaded stud 16 embedded in the apex 13 and a loose washer 18 of curved section resting against the head of the stud. The stud 16 may have a cross-pin 17. The diaphragm which is of vulcanized rubber or synthetic rubber-like material is provided with fabric reinforcement 11 which may be carried into engagement with the stud 16. The diaphragm is strengthened by radial ribs 19 which become progressively thinner from the centre out to the bolt holes 21. Alternatively, or in addition, the diaphragm may taper in section towards the margin. Specifications 657,324 and 693,845 are referred to.

Title: Preparation of cytosine and intermediates
Inventor: TARSIO PETER JOHN
IPC: C07D239/47
Filed: 1957-04-26
Abstract: Cytosine is prepared by reacting a b -alkoxy-acrylonitrile, containing 1-10 carbon atoms in the alkyl group, with urea in a solution containing an alkali metal alcoholate and an alcohol at 75-115 DEG  C.  Preferred conditions are the use of b -ethoxyacrylonitrile with sodium methoxide at 75-85 DEG  C. and with sodium n-butoxide at 112-115 DEG  C.  After the reaction the produced alcohol may be removed, sulphuric acid, e.g. of concentration 2N, added, the mixture heated to about 80 DEG  C., ethyl alcohol added over one hour while maintaining the temperature at 80-85 DEG  C., the mixture cooled to about 20 DEG  C., the separated cytosine sulphate filtered and dissolved in water, 29 per cent ammonia added, and the cytosine separated, dissolved in water, decolorized with charcoal and cooled to about 20 DEG  C. with deposition of cytosine.  The b -alkoxyacrylonitrile starting material may be prepared by (i) reacting isoxazole with an alkali metal alcoholate containing 1-10 carbon atoms preferably at a temperature at least as low as 10 DEG C., to form an alkali metal cyanoacetaldehyde, and reacting the latter with an alkyl chloride, bromide or iodide, preferably ethyl iodide, at substantially the boiling temperature of the mixture; (ii) reacting an alcoholic solution of isoxazole with an alkyl ester of sulphuric, phosphoric, boric, benzene sulphonic or toluene sulphonic acid in which all of the acidic hydrogens are replaced by alkyl (preferably diethyl sulphate), at 10 DEG  C., adding an alkali metal hydroxide while maintaining a temperature of 5-10 DEG  C., removing formed alcohol at atmospheric pressure, and adding water and steam distilling.  The isoxazole may be prepared by reacting, at 60-70 DEG C., hydroxylamine hydrochloride and a malonaldehyde diacetal, preferably malonaldehyde diacetal itself, cooling, e.g. to 20 DEG C., neutralizing the liberated hydrochloric acid with sodium carbonate, adding water, extracting with ether and removing ether. Examples illustrate all the above procedures.

Title: Improvements in or relating to coal cutting machine installations operating upon a remote control
IPC: E21C31/12
Filed: 1935-05-07
Abstract: 448,655. Protective cut-out arrangements. SHEVLIN, J. T., 15, South Street, Finsbury, London.-(Siemens-Schuckertwerke Akt.-Ges.; Siemensstadt, Berlin) May 7, 1935, No. 13482. [Class 38 (v)] A coal-cutting machine installation operating on remote control by means of an automaticallyoperated control switch, the operating coil of which is arranged to be connected to a source of potential through operation of a remotelycontrolled switching-in relay, has the switching in relay and a no-volt release coil connected in parallel when the control switch is off, and in series with a resistance which is of such value as to ensure that the switching-in relay can only be operated when the resistance is shunted by a small resistance, for example, short-circuited by closure of the remote-control switch. Closure of switch 20 short-circuits the resistance 21 in the control circuit 17, 18, thereby sufficiently energizing the switching-in relay 12 from the secondary of transformer 9 to close its contacts and energize the closing- coil 10 of the switch 8. The latter, on closing, opens at 22 the circuit of relay 12, and is latched closed by the no-volt coil 11 which'does not release when the switch 20 is released. If the switch 8 opens on overload, the relay 12 is not sufficiently energized to re-close it until the switch 20 is operated. A manual switch 19 is provided for cutting-off the motor. The switches 19, 20 can be combined in the reversing drum-switch, Fig. 2 (not shown), having two switching-in positions and a tension spring for automatically moving to the appropriate working position when the handle is released.

Title: Improvements in or relating to lathes or other machine tools
IPC: B23Q5/26
Filed: 1949-05-20
Abstract: 682,072. Lathe detail. KOHRING, E. May 20, 1949, No. 13557/49. Class 83 (iii). [Also in Group XXIX] The hydraulically-operated tool slide 14 of an automatic lathe or other machine tool is controlled by a slide valve 7 which is operatively connected to both a feed cam 1 and a working piston 13 so that the cam determines the movement of the slide valve to admit fluid to the working piston and move the tool slide to a predetermined depth of cut, and this movement of the tool slide re-sets the slide valve to maintain this position; the initial depth of cut may be large and then gradually decrease to give a finishing cut. A lever 4 is biased by a spring 3 to bear on the cam surface 1 of a rotating drum 2 and is adjustably connected by a pin 32 in a slot 33 and a connecting rod 5 to a floating lever 6 which is pivoted at 7a on the control valve and at 8 on a ring 10 spring- pressed against an adjustable stop 12 on the piston rod of an auxiliary piston 9. For the downward feed stroke of the tool slide 14 by the working piston 13, corresponding to the rise of the cam surface, the control valve is moved to the left, permitting fluid from a pump 23 to flow past the land 22 to the upper side of piston 13. Fluid on the underside of piston 13 then passes through a pipe 15 and moves the auxiliary piston 9, thus moving the lower pivot point 8 of the lever 6 equally and in the opposite direction to the movement of the upper pivot 27 so that the valve opening remains constant until a change in the pitch of the cam 1 alters the opening to move the piston 13 and tool slide to give a new depth of cut. When the fall of the cam surface is reached, the spring 3 causes the slide valve 7 to be moved to the right to give an opening at 28 by which the fluid above the piston 13 can be exhausted, the piston being moved up by fluid forced through the pipe 15 by the pump pressure acting on the auxiliary piston. The return stroke is under the control of the cam surface until a set screw 30 bears against the end of the valve 7 and maintains the opening 28 so that both pistons 9 and 13 move up to their end stops 16 and 17 ready for another feed stroke. If the pistons are slightly out of synchronism, fluid behind the leading piston by-passes through a valve 20 or 21. For controlling several slides, the cam drum may be replaced by separate cam discs.
